In a bid to earn the distinction of being the best possible mobile service and coverage in town, New World PCS 009 Digital Connection became the first PCS network in Hong Kong to deploy a second Mobile Switching Centre, ( MSC ).

A dedicated " sub-time slot " ( 16 kbit / s ) is allocated from the base station to the transcoder, and finally, another time slot ( 64 kbit / s ) is allocated from the transcoder to the Mobile Switching Centre ( MSC ).

Multiple fibre connections can be used to provide redundancy to voice and data connections between switching centres, but careful network design is required to avoid situations where a main fibre and its backup both go through the same damaged central office as a potential common mode failure.

During the introduction of International Direct Dialling ( IDD ), initially referred to as International Subscriber Dialling ( ISD ) within the UK, Group Switching Centres were equipped with international call timers and international register-translators to route calls to the relevant international exchange for onward routing abroad.

Another overlooked aspect of mobile latency is the inter-network handoff; as a customer on Network A calls a Network B customer the call must traverse two separate Radio Access Networks, two core networks and an interlinking Gateway Mobile Switching Centre ( GMSC ) which performs the physical interconnecting between the two providers.

If it was not a local call and therefore to be routed out of the exchange, then it would tell the register to come back with each digit until it could decide on the routing, as not all calls went to the GSC ( Group Switching Centre ) as there was AAR ( alternative available routing ).

The GSM 03.40 TPDUs are used to carry messages between the Mobile Station ( MS ) and Mobile Switching Centre ( MSC ) using the Short Message Relay Protocol ( SM-RP ), while between MSC a Short Message Service Centre ( SMSC ) the TPDUs are carried as a parameter of a Mobile Application Part ( MAP ) package.

Major sectors of the Indian telecommunication industry are telephone, internet and television broadcast Industry in the country which is in an ongoing process of transforming into next generation network, employs an extensive system of modern network elements such as digital telephone exchanges, mobile switching centres, media gateways and signalling gateways at the core, interconnected by a wide variety of transmission systems using fibre-optics or radio broadcasting in India.
